IMPROVED CABLE-STOPPER.

Specification forming part of Letters Patent No. 55,343, dated June 5,1866.

1'0 alt .whom it may concem:

Be it known that I, PETER MURRAY, of the city and county of Milwaukee,in the State of Wisconsin, have made new and useful Improvements inOable-Stoppers and I do hereby declare the following-to be a full,clear, and exact description of the nature, construction, and operationof the same, snflicient to enable one skilled in the art to which it isallied to construct and use the same, reference being` had to theaccompanying drawings, which are made a part of this specification, andin which- Figure 1. is a top view. Fig. 2 is an elevation of the same.Fig. 3 is a section on the line a b, Fig. 1. Fig. 4is a section ontheline c d, Figs. 1 and 2.

The invention consists of a cable stopper or .clutch, for the purpose ofholding a line, rope,

cable, or hawser over the side railing or bulwarks of a ship, (lock, orwhart', for the purpose of sat'ely, expeditiously, and effectuallyarresting its mot-ion.

The ordinary position of the clutch will be upon the rail A ot' a ship,over which the rope B runs or is paid out.

The device consists of sliding jaws O O' and a stationary center pin, D,the rope B being pressed against the pin D by the pressure of theslidingjaws O O', which are caused to approach each other by means ofthe engagement of the pins E with the oblique slots F in the wheel G,which is revolved by the lever H and retained at a given point by thepawl and ratchet I J.

The rope may be Wrapped around the center pin, D, or pressed against oneside of it only. In the latter case, by making one jaw permanent and theothermovable, a center pin may be dispensed with and the projecting faceot' one jaw be caused to pinch the rope against a correspondingdepression in the other.

K is a bracket holding the inner end of the rotating shaft. The jawsslide in dovetail rabbets on the rail of the ship or`ot-her structure towhich they are attached.

Thep'in upon the lower end or ends ot' the projections from the jaws maybe en gagedby any cam or eccentric which will have the effect ot' movingit or them toward the stationary device against which the rope is to beclamped, or two connecting-rods united by wrists to the jaws and wheelmay have a similar effect.

The required pressure is brought to bear by I means of the lever H.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The combination of the movable jaws orjaw C O' with the stationary pinor jaw D, eccentrically-slotted wheel G, and lever H, all constructedand arranged to operate snbst-antially as and for the purpose hereindescribed;

PETER MURRAY.
